5 Global Health Issues to Address in 2023

The global health system has encountered various setbacks over the past three years, hindering progress on multiple fronts. Nevertheless, local frontline health workers, government agencies, and health systems have made significant strides in combating disease outbreaks. However, natural disasters, climate change, and global conflicts have disrupted local health services, making it critical to focus on rebuilding health systems, regaining lost progress, and addressing challenges as we move into a post-pandemic era.

It’s difficult to predict what global health issues will emerge in 2023, as new challenges can arise unexpectedly. However, based on current trends and ongoing challenges, here are some of the global health issues that may require attention in 2023:

1- Pandemics and primary healthcare services:

Outbreaks of diseases on a pandemic scale pose a significant global health challenge and can cause immense harm to public health, social and economic stability, and national and international security. Pandemics such as COVID-19, SARS, and H1N1 have highlighted the need for robust pandemic preparedness and response measures.

Addressing pandemics requires a comprehensive approach that involves detecting outbreaks early through surveillance and monitoring. Moreover, it requires preventing and controlling the spread of infectious diseases through measures like vaccinations, quarantine, and contact tracing. There’s also a greater need for continuous medical research and advanced technology to develop new treatments, vaccines, and diagnostic tools.

In addition to the various measures to address pandemics, having trained professionals is critical in combating these global health threats. Due to the popularity of online programs, it is much easier for anyone to enroll in a Masters of Public Health online degree program and acquire the necessary expertise and knowledge from an accredited institute. Trained professionals can help identify and respond to outbreaks early, which is crucial in preventing pandemics from spreading rapidly and causing widespread harm.

2- Continuing the battle against noncommunicable diseases:

The prevalence of NCDs has been increasing globally in recent years, and they now account for a significant portion of the global disease burden. In fact, according to the World Health Organization (WHO), NCDs are responsible for around 71% of all deaths worldwide.

NCDs are chronic diseases that typically develop over a long period and are often caused by genetic, environmental, and lifestyle factors. Some common examples of NCDs include heart disease, stroke, cancer, diabetes, and chronic respiratory diseases. Several risk factors contribute to the development of NCDs, including unhealthy diets, physical inactivity, tobacco use, and the harmful use of alcohol. These risk factors are often intertwined and can compound the risk of developing NCDs.

Taking comprehensive measures to tackle the global impact of NCDs is crucial. These strategies include promoting healthy lifestyles, improving access to healthcare services, and implementing policies to reduce exposure to NCD risk factors.

For example, healthcare providers can play a significant role in preventing and managing NCDs. They can offer education and guidance to their patients regarding healthy lifestyle choices, such as incorporating regular exercise, maintaining a balanced diet, and quitting smoking. Governments can also take steps like taxing tobacco, limiting ads for unhealthy foods, and promoting physical activity through urban planning to improve public health.

3- Health Impacts of Climate Crisis:

Climate change is one of the biggest health threats facing humanity. And unfortunately, it’s only getting worse. Nearly half the world’s population lives in places highly vulnerable to climate change. If we don’t take further action, it’s estimated that 250,000 people will die each year due to climate change between 2030 and 2050.

From air pollution and food production to heat waves and extreme weather, climate change is damaging our health in ways that are fatal. And as it accelerates, we can expect to see even more conflict and displacement, which can lead to large outbreaks of infectious diseases.

Addressing the health impacts of climate change will require a multi-pronged approach that includes mitigation and adaptation strategies. Mitigation strategies focus on reducing greenhouse gas emissions to slow the pace of climate change, while adaptation strategies aim to help communities adapt to the changes already occurring.

Examples of mitigation strategies include transitioning to renewable energy sources, improving energy efficiency, and reducing emissions from transportation. Adaptation strategies may involve improving access to clean water, developing heat warning systems, and implementing mosquito control measures.

4- Mental Health Concerns:

According to the World Health Organization, mental health issues are a leading cause of disability and contribute significantly to global health issues. In recent years, mental health issues have become more widely recognized and accepted as legitimate health concerns. However, stigma and a lack of access to resources continue to be barriers for many people seeking help.

The COVID-19 pandemic has only highlighted the need for increased attention to mental health. The social isolation, financial stress, and uncertainty caused by the pandemic took a toll on people’s mental health and well-being. While many people have coped well, others have experienced increased anxiety, depression, and other mental health issues.

To address mental health concerns in 2023, we need to work together as a society to break down the barriers to accessing mental health care. It could involve increasing funding for mental health services, reducing stigma through public education campaigns, and improving access to evidence-based treatments.

5- Healthcare accessibility:

Healthcare accessibility affects the ability of individuals and communities to obtain the care they need to maintain their health and well-being. Various factors can hinder individuals from accessing healthcare, such as their geographical location, income level, educational background, and social standing.

In 2023, healthcare accessibility is likely to be a significant concern due to the ongoing effects of the COVID-19 pandemic. The pandemic has highlighted disparities in healthcare access and has exacerbated many of the underlying social and economic factors that contribute to these disparities.

In many low- and middle-income countries, access to healthcare services is limited due to inadequate infrastructure, shortage of healthcare workers, and limited funding. Even in high-income countries, access to healthcare is not universal. Many people, particularly those living in rural areas, face significant barriers to accessing healthcare services. These barriers can include long wait times, high costs, and limited availability of specialized care.

Improving healthcare accessibility will require a coordinated effort that involves healthcare providers, policymakers, and communities. To make healthcare more accessible, it is crucial to invest more in healthcare facilities, make healthcare more affordable, and create policies ensuring access to healthcare for all.


These are some of the global health issues that may require attention in 2023, but emerging health concerns can arise unexpectedly. Being prepared to respond quickly and effectively to new and unexpected health challenges is crucial for protecting public health and minimizing the spread of diseases. It requires ongoing investment in research, surveillance, and infrastructure to ensure that healthcare systems rapidly detect and respond to emerging health threats, both now and in the future.
